Need Help Finding Your Ring Size?

The most accurate way to determine your ring size is with our complimentary ring sizing kit.

If you're unable to use a sizing kit, the methods below can help you estimate your size. Please note that at-home measuring methods are only estimates and may not be perfectly accurate.

Method 1: Measure an Existing Ring

1. Choose a ring that comfortably fits the intended finger.
2. Measure the inside diameter of the ring (the distance across the center from one inside edge to the other) in millimeters.
3. Compare your measurement to the chart below.

Method 2: Measure Your Finger

1. Wrap a thin strip of paper or a piece of string around the base of your finger.
2. Mark the point where the ends overlap.
3. Measure the length in millimeters.
4. Compare your measurement to the circumference column in the chart below.

Helpful Sizing Tips

• Measure your finger at room temperature.
• Fingers tend to swell throughout the day, so avoid measuring first thing in the morning.
• Wider bands generally fit more snugly and may require a slightly larger size.
• If you're between sizes, we typically recommend choosing the larger size.

Our Ring Sizing Promise

We offer a complimentary first resizing on most rings within one full size up or down.

Example: If you order a size 6 and need a size 5 or size 7, we'll resize it for you at no charge.

If a ring requires sizing beyond one full size, certain styles may need to be remade rather than resized. In those cases, additional charges may apply. We recommend getting as close as possible to your correct size before placing your order.
